A brilliant hidden camera show that aired on MTV in 1996. Dave, Travis, and Frank drove around in a white van developing practical jokes to play on anyone, anywhere. Classic pranks include the Spring Break Shuttle Bus, and "Super Duper Shopping Experience". The logo for the show was a yellow smiley-face with crosshairs over it. Should definitely be in syndication...
